Abstract

We have used a new technique, endoscopic staple-assisted esophagodiverticulostomy (ESED), for the treatment of Zenker's diverticulum. This technique is a modification of the endoscopic approach first described by Mosher1 in 1917 and popularized by Dohlman and Mattsson2 in which the common wall between the esophagus and diverticulum was divided without mucosal closure. ESED differs in that an endosurgical stapler is used to create an esophagodiverticulostomy by dividing the common wall between the esophagus and diverticulum, with the mucosal and muscular edges sealed by the staples. We have performed this procedure in six patients, with no perioperative morbidity in any patient. All patients resumed oral intake on either the first or second postoperative day, with no evidence of fistula formation or mediastinitis. Hospital stay has averaged 2 days (range, 1 to 3 days). Patient follow-up after ESED averages 6 months and is available for five of the six patients treated. There has been complete resolution of pretreatment symptoms in these five patients, with resumption of regular diet between postoperative day 3 and day 14 (average, day 9). Our results demonstrate that ESED is a safe and effective treatment for Zenker's diverticulum. This endoscopic approach offers a number of advantages over previously used treatments for Zenker's diverticulum, including reduced morbidity, rapid convalescence, short hospitalization, brief operative time, and predictable resolution of symptoms.
